HTML purifier

[AcidLava]

Hello,

On Prestashop 8.2.3, when I add something like loading="lazy" in the source code of an element via the text editor, it disappears as soon as I save (because of HTML Purifier?)? This is quite problematic, since even when writing a blog post, the code gets completely altered at the slightest mistake.

What's the cleanest solution to work around this issue?

Thank you.

As an option, add an attribute to the HTML Purifier configuration

 

PrestaShop allows you to extend the list of allowed attributes in HTMLPurifier_Config. This is done by overriding TinyMCE / CMS Controller, for example in a module or override.

I tried this via Tools.php but it doesn't work.

 

<?php

class ToolsOverride extends Tools
{
    public static function purify($html, $uri_unescape = false)
    {
        static $purifier = null;
        if (!$purifier) {
            require_once _PS_TOOL_DIR_.'htmlpurifier/HTMLPurifier.standalone.php';
            $config = HTMLPurifier_Config::createDefault();

            // Ajout de l’attribut "loading" pour les balises <img>
            $def = $config->getHTMLDefinition(true);
            if ($def) {
                $def->addAttribute('img', 'loading', 'Enum#lazy,eager,auto');
            }

            $purifier = new HTMLPurifier($config);
        }

        return $purifier->purify($html);
    }
}

Ovveridethe purifyHTML method in Tools.

Add attributes to an existing tag:

$def->addAttribute(‘a’, ‘data-locale’, ‘Text’);

 

Add a new tag:

$def->addElement(‘canvas’, ‘Block’, ‘Flow’, ‘Common’, [‘data-url’ => ‘URI’]);
